Project Blue Book Case File
OLD GREENWICH, CONNECTICUTAugust 1955
Summary
In August 1955, a man in Old Greenwich, Connecticut shot what he believed to be a color photograph of a flying saucer. The object appeared as a small, bright blue-white point of light moving across the sky in a horizontal path from south-southwest to north-northeast. The photographer used a Kodak Pony camera with fast film to capture the image, describing the object later as roughly 150 feet in diameter and disc-shaped, made of light metal.
The Air Force launched a thorough investigation. Photo specialists from ATIC (Air Technical Intelligence Center) and WADC (Wright Air Development Center) subjected the color transparency to microscopic, macroscopic, and other examinations. Both teams independently concluded that the object was not a spacecraft or meteor, but rather a flaw in the film emulsion, probably caused by a chemical reaction during the color processing. The trail behind it resulted from what photographers call "bromide drag," a processing artifact.
The official analysis raised several red flags about the observer's account. The transparency showed the tiny object almost perfectly centered in the frame, which investigators found remarkably difficult to explain if the observer had truly spotted such a small, fast-moving object in a dark sky and framed it so precisely. The observer's written statement also contained inconsistencies. He described the object as "the size of a head of a pin" while simultaneously claiming it was 150 feet in diameter and disc-shaped with visible structural details. Furthermore, the fast shutter speed of the camera would have made recording any visible trail extremely improbable at the claimed distance.
In a separate inquiry, an astronomer contacted the observer for more details but was unable to reach him at the address provided. These factors led the Air Force to conclude the case was a deliberate hoax, with the observer possibly finding the film defect first and then fabricating a UFO report to match it.
